Table 1.

Basic properties of the Messel Shale food webs. (S, number of taxa; L, number of trophic links; L/S, linkage density and C (L/S²), directed connectance. Cert-Low, Cert-Int, Cert-High indicates the percentages of links that are low, intermediate or high certainty. ‘Red.’ refers to reduced web versions that exclude low-certainty links and associated taxa. ‘Tro.’ refers to trophic species web versions.)
